There’s a creepy new accusation in the sexual-harassment probe of Assemblyman Vito Lopez — that he even leered at a 14-year-old intern and made comments about her sexy attire, sources told the The Post.

“He made comments about a 14-year-old intern, how attractive she dressed, and he wanted one of the female staffers to dress in a sexy way like this 14-year-old,” said one of several sources familiar with the ethics probe.

Lopez’s behavior around a minor was just one of the shocking findings to emerge from testimony submitted to the Joint Commission on Public Ethics.

Several sources also said Lopez had a fetish: He urged female employees to rub his hands when he claimed they went numb.

“He asked them to massage his hand. He claimed he needed it for some medical reason,” said one source familiar with the Lopez investigation.

A second source close to the probe added, “Some people are into feet. He’s into hands. It’s just his thing.”

The sources also said JCOPE is looking into an accusation that Lopez booked a single hotel room on a trip to Atlantic City and expected a female staffer to share it with him.

“He got a room, and one of the female staffers was adamant that she not stay overnight with him,” the source said.

Lopez’s attorney did not respond to a request for comment. Lopez has previously denied allegations he sexually harassed at least four women on his payroll.

The lascivious behavior, chronicled over months of interviews with former staffers and others, was presented to JCOPE commissioners by staff in a closed-door meeting yesterday.

JCOPE must now decide whether to recommend the Assembly take further action against Lopez.

In August, the Assembly Ethics Committee unanimously determined that Lopez had violated chamber rules after two young female staffers complained that he sexually harassed them. The Brooklyn pol was later censored and stripped of his leadership post.

Soon after that action, it was learned that the Assembly’s leaders had earlier settled a separate case with two other female staffers, awarding them a secret $103,080 settlement in response to claims Lopez had groped them.

A second criminal investigation of Lopez is also being conducted by Staten Island District Attorney Dan Donovan’s office.

Meanwhile, Assembly Speaker Sheldon Silver, who agreed to pay the two former staffers the big bucks in hush money, insisted yesterday he is cooperating with JCOPE.

“We believe in the end, their findings will be consistent with showing that at the time we acted in good faith in what we believed were the best interests of the victims,” he said.
